Converter circuit and electronic system comprising such a circuit

摘要

The circuit (2) has a control unit (53) arranged to control changes in duty cycle of a chopping circuit (11) based on a reference signal of a regulation loop (57). The regulation loop includes a storing unit for analogical storing of information corresponding to output voltages from an electrical energy source (3). The regulation loop includes an analog comparison unit delivering the reference signal increasing or decreasing the duty cycle by the control unit based on the stored information.
